matrix a is shown below. given that matrix a equals matrix b, what is the value of $b_{23}$?\n$a = \\begin{bmatrix}2&0&-9&11\\18&-7&0&21\\end{bmatrix}$\n-9\n-7\n0\n21
Answer
Explanation:
Step1: Understand matrix notation
In matrix notation $b_{ij}$, $i$ represents the row - number and $j$ represents the column - number.
Step2: Locate the element in Matrix A
Since $A = B$, to find $b_{23}$, we find the element in the 2nd row and 3rd column of Matrix A. In Matrix $A=\begin{bmatrix}2&0& - 9&11\18&-7&0&21\end{bmatrix}$, the element in the 2nd row and 3rd column is 0.
Answer:
C. 0
